To all whom lit may concern.'

Be it known that I, RAYMOND HANUs, a sub# ject of the King of Belgium, residing vat Brussels, y Belgium, have invented certain new and useful Improvements in Typewriters, Lof which the following is a specification. y

Commercial necessities require that it should berpossible to write on a special single sheet which forms a check or control and also a copy, inscriptions which are made on a series of separate sheets. This is chiefly the case when it is desired to add the amounts of various receipts that have been written on the machine. Reproduction of these inscriptions on the control sheet is generally done by means of carbon paper, the separate sheets, such as for instance receipts, being introduced one after another' into the paper support of the machine. The drawback of the said method is that the in dications on the copy are spaced at avdis- I tance apart dependent upon the dimensions of the forms. In fact, the platen roller which carries the papers, must be moved to the extent of several notches, corresponding to line spaces, for making the inscription on a separate sheet and then on the next one.

`These drawbacks are avoided in the present invention owing to the control sheet eing driven by the ordinary mechanism which produces the advance orfeed, that is to say to its being advanced tothe extent of one notch equivalent one line space foreach return of the carriage, Whilst the 'separate sheets are'operated by an independent device which enables them to be moved on l the carriage whilst the control sheet remains fixed. l

Moreover, means is provided for cutting into separate sheets paper supplied from a continuous strip or rol.

The invention provides special devices for the case in which the separate sheets are moved by hand, or automatically by the return of the carriage.

It provides also special devices for the Figure l isa general' view of the invention, the forms being movedby a hand operated mechanism, for the case in which only one line of inscription is-to be written on each form. l

Figure 2 is a cross-section of Figure l and shows the principle of the invention'. For the sake of clearness the thickness of the sheets has been greatly exaggerated.

Figure 3 shows a device automatically ensuring the movement of the paper by the return of the carriage, with one line of inscription per form.

Flgure 4 shows thehand driving device for the case in which several lines of inscrip-I tion are to be written on each form. Figure 5 shows an automatic device for the latter case.

The carriage l which carries the sheets-is moved in the usual manner on the frame '2' of the typewriter. On the said carriage are mounted: (l) the platen roller 8 on which are placed the copy sheet 4 and the carbon paper sheet 5 and (2) the apparatus which guides, drives, and cuts the forms. The roller 3 is rotated at each return of the carriage to an extent equal to a line space; and the said carriage comprises two plates or standards 6l and 6 which support the roll ot' forms?, the paper guides and the feed roll shafts 8 and 8', and ,the device Jfor cutting the typed sheets.

The rst form 9 is introduced together with thev carbon Sheet 5 and the tally sheet 4 which is to form thea copy, behind the platen 3 which is turned by means of a handswheel 10 until the sheets are brought in frontof the type.

The sheets 4f and 5 are held on the platen 3 by means of the usual pressing or clamping devices. Two brackets 11 and-11 which are pivoted about pins 12 and 12 respeccase in which only one line is to be inscribed sively and to which are secured lthe. cutting on each of the separate sheets, or forthat in which several lines of inscription are necessary. v

The accompanying drawings illustrate by way of example several constructions acl cording to the invention for the case in which theseparate sheets are obtained by device and one of the feed roll shafts 8 for guiding the paper 9 are then turned down on their plvot pins.

`The device which'will be hereinafter described ensuring the advance of the form 9, is operated until the line on which the inscription is to be made, is broughttothe level of the type. The brackets 11 and 11 b e written on the forms, and the advance of thepaper`9 is effected by hand, the work is done in the following manner After having written the desired indications, the sheet 9 is moved by operating a handle which drives a wheel 16 mounted on a spindle 17 on which is a toothed wheel 18 which engages with a wheel 19. The latter Wheelacts on gears 20 and 21 mounted on the feed 'oll shafts 8 and 8 respectively.

' The shaft 8- is secured to the two plates 6 `and' 6', and the shaft 8 is mounted'in the brackets 11 and 11.

In the case in which the inscription is' y made on any desired alignment of the form,

and the latter has an arbitrary length, the

handle 15 is operated until the sheet 9 is' brought to a mark indicating the height or level. of the type. The inscription is then made, whereupon the operator continues to turn' the vwheel 16 until the lower edge of the'form is brought to the level of the knife,

in order to enable it to be .cut to. the required len h.

If howeverthetyping is done on forms of' a given size, on which only one line is typed, the wheel 16 is provided with a small recess 22 with which engages a roller 23 which 's\ mounted on the end of a lever 24 constantly pulled upwards'by a spring 25. This stop locks the advance or feed device, stops the paper at the level of the knife, and xes the alignment of the next form at the height or level lrequired for making the necessary inscription.

It must be polnted out that for each size.

of forms, it is necessary'touse a set of ear wheels producing the desired special eed or advance.

If 1t is, required to write several lines on one and the same form, and it is desired to -obtain an exact line space on the latter, the

device vshown in Figure 4 is adopted, in

" which on one and the same spindle 17 are mounted the' wheel 16, the wheel 18 driving the feed roll shafts 8 and 8l (Figure 1), and

' a notched wheel'26 constructed substantially similar to the one which effects the spacing" l .fof-the platen-3. A roller 27 on a lever 28 1 passes, on .a slight movement of the handle l15, from .one notch of wheel 26 to the next,

'and the.-v form 9 is therefore fed forward to the extent of a line space, whilst the carbon @papersheet 5 and the copy 4 are fed forward to the same extent'automatically by the .reyturn'of the carri A hand-operatgeca'm or other' device 18 of .a suitable shape makesit possible to dis- -of the type,

engage the vlever 28 carrying the roller 27 when the marks indicating the line spaces are no longer necessary.

Another construction is shown in Figures '3 and 5. In this construction the return of the carriage is utilized for producing the advance'of lthe three sheets in the desired proportions. f .tf

To that end, a rack 29 issecured to the frame 2 by means of brackets 30. Under the said rack travels a toothed wheel 31 mounted on'a spindle 32 secured to the carriage 1 and transmitting the movement by means of a bevel wheel 34 to a gear wheell 33 and thence to the wheels 20 and 21, the latter two being secured asbefore stated to the feed roll shafts 8 and 8 respectively. The said spindle 32 rotates in brackets 35 and 35 which form bearings.

The spindle 32 is provided with a freewheel clutch 36 such that the bevel wheel 34 is rota-ted when the carriage 1 returns to theline, and remains stationary when it is moved in 'the direction enabling indications to be written. A spring 37 keeps the free wheel clutchv 36 in engagement during the movement in the two directions of the carriage 1. i

The length of the rack and 'the gear wheels are calculated for a given size of forms.

The line on which the indications are to be inscribed, will be brought direct to the level without it beine* `necessary to make any lnew'manuvre. lt will be seen that the return of thecarriage feeds the copy sheet 4 forward in the ordinary manner, to the extent of a line space, so that the inscription can be made on the next form.

If it is desired to write several lines on one and the same form, the device shown in Figure 5 will be used. In such a case, in addition" to the elements shown in Figure 3, will be used'a device by means of which the free wheel'clutch 36 can be disengaged and, by the same movement, the gear wheels controlling the movement of the platen 3 which carries the copy sheet, and the wheels which drive the feed roll shafts-Sand 8.

To that end, a key 38 is supported by a bracket 35 behind which it can be keyed. This key can shift the movable member of the clutch 36 out of engagement with the fixed member thereof, by means of a yoke on said key whichcoacts with the groved hub 39'of said' movable clutch part.- At the same time the key acts ona' lever 4 0 pivoted I about a pin/ 40' and serving to shift a toothed Wheel 41 into mesh with a. wheel 49 and also with the wheel 33, the former of which is bevel wheel 34 will cease to a'ct on the wheel 20, so`that the rack 29 will no longer'act in order to move the form 9. The gear'wheels i are so calculated that the movementl f the platen 3 to the extent of a line space produces an identical advance of the sheet 9.

On the key 38 being returned to the position illustrated, the rack 29 will act during the next return of the carriage 1 on the paper 9 which will be advanced to the amount required.

The-device enabling'the forms to be cut after typing is shown in Figures l and 2. A circular knife 42 can rotate about aspindle 43 'and is held in p-lace by two cylindrical guides 44 and 44'; the knife could be constituted if necessary by a fine rigid blade. The spindle 43 is mounted on a sleeve 45 which slides on a rod 46 of squarefor other cross-section. The knife blade passes through a slot provided ina bar 47.' The paper 9 to be cut is pressed against the said bar by two rollers 48 and 48 mounted on the spindle 43. By sliding the carriage supporting the knife 42, on the guide 46, the form will be neatly cut in one operation to the desired size. i

A suitable arrangement of the gear wheels makes it therefore possible to make inscrip- 'tions on forms of given length and at clearly,

specified alignmentlevels, the stoppage of the advance movement of the sheet 9 being marked exactly. Moreover, the apparatus can also be adapted for typing on sheets of any desired length, and at any.point 0f the said sheets, the cutting and the inscription being done with the assistance of clearly visible marks. Owing to the advance of the sheet 9 being independent of that of the copy 4, the latter will be moved at each return of the carriage only to the extent of one line space, whatever be the size of the form and the position of the inscriptions, on the latter.

The apparatus could be fitted to any typewriters provided with a movable carriage, with or without automatic return.
